原七年級(jí)英語下冊 Unit 8 Is there a post office near here（第3課時(shí)）(Grammar Focus3c)同步語法精講精練課件 （新版）人教新目標(biāo)版

第三課時(shí)(Grammar Focus3c)單元同步語法精講精練定義：there be句型也稱為“存在句”，表示“某地有某物”。用法及構(gòu)成there be句型結(jié)構(gòu)為：There be名詞(主語)地點(diǎn)副詞/介詞短語(表示地點(diǎn))。there be句型屬于倒裝句，主語通常放在謂語后面，動(dòng)詞be為謂語。be動(dòng)詞應(yīng)根據(jù)主語的單復(fù)數(shù)而變化，主語是單數(shù)，用there is；若主語是復(fù)數(shù)用there are，若主語是不可數(shù)名詞，則用there is。eg：There are 50 students in our class.我們班有50個(gè)學(xué)生。there be句型中的謂語應(yīng)和后面的主語保持一致，若有兩個(gè)或兩個(gè)以上的主語，動(dòng)詞be的形式應(yīng)由和它位置最近的那個(gè)主語的人稱數(shù)決定。即遵循“就近原則”。eg：There is a pen and two books on the desk.桌子上有一支鋼筆和兩本書。There are two books and a pen on the desk.桌子上有兩本書和一支鋼筆。there be句型的否定句，直接在be動(dòng)詞后加not；其一般疑問句，要將be動(dòng)詞放在句首?？隙ɑ卮馂閅es，there is/ are；否定回答為No，there isnt/ arent。【注意】若there be句型的否定句和一般疑問句中有some時(shí)，則應(yīng)將some改為any。There be句型一般現(xiàn)在時(shí)的特殊疑問句由“特殊疑問詞主語is/ arethere地點(diǎn)狀語”構(gòu)成，有時(shí)地點(diǎn)狀語可省略。答語不能用Yes或No，需根據(jù)情況直接回答。eg：How many apples are there in the bag？包里有多少蘋果？Five.五個(gè)there be與have/ has的區(qū)別there be結(jié)構(gòu)表示客觀存在，意為“某地有某物(人)”；have/ has表示所屬關(guān)系，意為“某人擁有某物”。eg：There is a TV in our classroom.在我們的教室里有一臺(tái)電視機(jī)。We have a TV in our classroom.我們有一臺(tái)電視機(jī)在教室里。next to 緊挨著，與相鄰near 在附近behind 在后面across from 在對面in front of 在的前面(范圍之外)【拓展】in the front of 在的前面(范圍之內(nèi)) 一、用be動(dòng)詞的適當(dāng)形式填空。(必要時(shí)可加not)1There _a pay phone near here.2_there any books in the bag?No，there _3There _an apple and two books on the desk.4_there an English boy in the room?Yes，there _5There _some food in the kitchen.isArearentisIsisis二、從方框中選擇合適的詞或短語完成句子。6The post office is across _the bookshop.7My school is _Bridge Street.8Is there a hotel _here?9The pay phone is _the bank.10The park is _the restaurant and the supermarket.fromonaroundnext_tobetween三、按要求完成下列句子。11There are some apples on the tree.(改為一般疑問句)_apples on the tree?12There are some trees near the house.(改為否定句)There _trees near the house.13Are there any new storybooks on the bookshelf(書架)？(作否定回答)_ Are there anyarent anyNo，there arent
